i used rics circuit and did the dual transister design and all it did was rock back and forth and not fully spin up. any ideas? i used a smaller computer power supply fan which is a 3 inch. Could only get about 100 windings around each core. i used awg 26 wire. Any ideas why the motor would not spin up. I also tried one pole for power at 100 turns of awg 26 and the next 90 degree pole with 250 turns of thinner wire which was the trigger pole and the same thing occured it just rocked back and forth. Used a 1000kpot and a neon for each section and used 2n3055 transistors and used ecg519 for the base and emitter diode. Tried single and dual circuit just rocked. any help would be great and would be appreciated
